Application filed September 7, 1928. Serial No. 304,420.

In building of present day concrete structures such as roads, there isemployed a reinforcing structure such as steel rods which are extendedtransversely and in some instances longitudinally of the constructionand are embedded in the b'uilding'materials, usually concrete. Where itis desirable to have a permanent curb on the side of the road and at anelevation somewhat above the roadway, the reinforcing rods may beallowed to project beyond the roadbed and imbedded in the materialforming the curb prior to the paving of the road; the rods reinforcingboth the roadway and the pavement and constituting tie memberstherebetween.

In constructing a road in this manner, the curb may first be laid withthe rods in place, the concrete being poured in between the formsembedding the ends of the rods and forming a support therefor when theconcrete of the curb has taken its set. The curb constitutes in thismanner a support for the rods while the roadway is being laid in theusual manner as by'machines moving along 7 tracks at the side of theroadway.

It is seldom feasible to lay the curb and the roadway simultaneously,consequently, the utilization of tie members between the twoconstructions is of considerable importance.

This invention proposes an improved form of curb form whereby tofacilitate the laying of the reinforcing for combination road andpavement constructions. In the utilization of curb forms of thischaracter, when the curb has been completed and the materials have takentheir set, the curb forms are re; moved and may be used elsewhere for asimilar purpose. It is desirable therefore that the curb forms should beso constructed that the sections may be readily taken apart and removedfrom the projecting rods with a minimum manipulation of parts andwithout any unlatching operations.

A further desirable characteristic is that the rails should be soconstructed for the above purposes that the structure thereof will notbe weakened and will stand up with sufficient strength and durabilityfor the stress to which they are subjected.

In order to provide a device filling these requirements, I have evolveda curb form made of sections having a slip connection therebetween andformed with notches through which the tie rods may project. The strengthand durability of the construction is maintained by surrounding thesenotches with a marginal reinforce, which may be in the nature of aflange and which may provide further reinforcing of the side rail byhaving a bracket member formed thereon. In the construction, is alsoincluded, means for attaching the side rails to the ground which may bein the nature of boxes or yokes mounted on the base flange of thedevice, each having an aperture therein in alignment with an aperture insaid flange through which aligned apertures suitable stakes may bedriven into the ground on which the side rails are placed. 7

Other objects and advantages will appear in connection with the detaileddescription of the device which follows and will be incorporated in theclaims appended thereto.

In the drawings, constituting a part of this specification,

Figure 1 is a perspective view of a curb form made in accordance withthe principles of my invention showing the same from the rear aspect. a

Figure 2 1s a perspect ve-mew of the form viewing the same from the sideof the working face.

Figure 3is a detail fragmentarily showing a curb form having a notchtherein and illustrating the relation of a tie rod to said notch.

Figure 4 is a section on the line 44 of Figure 3.

Referring to the drawings in detail by reference numerals, the samenumerals, designating the same parts in all figures of the drawings, 10designates the curb form of which the present invention constitutes a'part. The form comprises the usual ground or base flange 11 adapted torest upon the ground, and an upright flange 12 having a working face 12which in practice defines the side of the road, curb or sidewalk, and isprovided at its top edge with a curved head portion 13 from whichextends downwardly the depending flange 14.- and which, with the I head13, overhang the base flange 11 protectively thereto.

the curb form is made in detachable sections which may be readily takenapart and are of such length as not to constitute too great a burden tothe workmen in transferring them from one place to another.

In order that the sections may be detached 2 with facility one fromtheother, the sections are each provided at opposite endswith membersdesigned-to interlock one with the other to hold the working faces ofthe various sections aligned within the same common plane. Any suitabledevice may be used forthis purpose. In the present embodiment the meansis disclosed in the form of a pair offlangesrespectively designated bythe numerals 14 and 15 positioned respectively on the adjacent ends oftwo contacting forms. The flange 14 is preferably in the nature of aflat piece of metal riveted or otherwise secured to the end of themember to which it is attached and lying flat against said member with aportion thereof projecting therefrom. The flange 15is preferably formedof a short length of angleiron with one flange 16 thereof secured in asuitable manner, as by rivets, to the base flange 11' of the other curbform and having a flange 17 extending upwardly therefrom in parallelismwith the flange constituting the working face or body of the device andspaced therefrom a distance equal to the thickness of the member 14*.

When the forms are placed together end to end as shown in Figure 1, themember 14;

will be projected between the flange 17 and the member 12 and will beheld in place by these members and the rebent portion 14 of the trackhead 13. The forms are also provided with suitable means whereby theymay be anchored to the ground against displacement or disarrangementfrom their proper alignment along the roadway. For thispurpose I haveused a well known construction in the nature of yoke members 18 havingparallellegs 19 secured to the ground flange 11, by flanges 20, and tothe upright portion of the device by flanges 21. The base flange 11'andthe arched connection 22 between the legs 19 are provided with alignedapertures through which suitable stakes 23 may be driven into the groundand held in position relative to the road rails by means of wedges 24passing through suitable slots in the legs. It will be noted that theyoke members not only constitute means cooperating with the mainstructure of the curb form for supporting the stakes 23 but alsoconstitute a substantial reinforce to the sheet metal construction ofthe road rail.

As has been above stated, it is frequently desirable to reinforce thestructure of the roadway by means of metallic structure such as tie rodsrunning in various directions within the aggregate of which the roadwayis constructed and where a permanent curbing is to be formed on themargins of the road or a sidewalk to be built'adjacent there to out ofmaterial similar to those used in building the roadway, it is customaryto allow the tie rods to project laterally from the roadbed and in orderto permit this, the curb forms are therefore constructed with slots ornotches formed at intervals therein corresponding to the position of therods.

These notches, which are designated by the numejral 25, are preferablyextended through the base flange 11 and about half-way up. the workingface 12. By this arrangement it is apparent that the sections of thecurb form may be lifted from astride the rods which are designated inthe figures by the numerals 26 and removed to another location forfurther use.

The weakening of the structure caused by the formation of these notchesis compensated for by the provision of marginal reinforcement in thenature of sheet metal flanges 27 and 28 extending transversely of themembers 11 and 12 and marginallyv of the slots or notches 25. Theconstruction of the device is further reinforced by bracket members 29with which the flanges 27 and 28 are integrally formed and which extendfrom the base member 11 to a position substantially at the top of themember 12 and into 0011'.

extending through the notchesv 25 andanchored in position by the stakes23, forms being positioned, of course on both sides of the proposedcurb. The aggregate may then be deposited between these forms in theusual manner by machinesrunning on suitable tracks of a well knowncharacter and after the finishing thereof may be allowed to set andobtain a predetermined hardness whereupon the stakes 23 may be removed.and the forms lifted section by section from their position. The curbsso formed may now be depended upon as a support for the rods until thepaving of the road has been completed.

. The simplicity of construction of this device makes for its facilemanipuluation. No bolts or locks are to be released except the wedges 24prior to the simple lifting of the sections apart and their removal fromone location of usefulness to another. No particular skill is necessaryin the manipulation of this device and there are few parts connectedtherewith which can get out of order.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States is:

1. A road rail of the class described, comprising, in combination, abase, an upright body, a head portion, the base having notches thereinwhich extend part way up the upright body, and reinforcing membersplaced adjacent said notches, secured to the base and engaging the underside of the head portion for reinforcing the road rail.

2. A road rail of the class described, comprislng, 1n combinatlon, abase, an uprlght body, a head portion, the base having notches thereinwhich extend part way up the upright body, and reinforcing members oneach side of said notches and engaging the under side of the headportion, the reinforcing members having flanges secured to the base andupright body portion.

In testimony whereof I affix my signature.
